PCIe Gen5 MCIO adapter
The Innocard EP4101 converts a PCIe x4 Gen 5 slot to an MCIO 38P interface with an included 100 cm cable to a U.3 connector. A built-in ReDriver extends 32 GT/s signals across four lanes and provides equalisation up to 24 dB at 16 GHz. Integrated clock buffer, SMBus switch and I/O expander manage power, reset and side-band signals for remote drive control.
Gen5 signal reach and management
The ReDriver and clock buffer allow longer PCB traces and cable runs while maintaining PCIe 5.0 link integrity at 32 GT/s. On-board TVS protection and a 3.3 V, 3 A load switch with reverse-current protection guard the host slot. Four status LEDs indicate add-in-card readiness, WAKE#, CLKREQ# and PERST# activity for out-of-band monitoring.
Taiwanese build for server chassis
Designed and manufactured in Taiwan, the adapter uses 30 µ gold MCIO connectors rated for repeated mating cycles. The 100 cm cable reaches drive bays in 2U or taller enclosures without stress on the motherboard slot. Green LEDs give immediate visual confirmation of link training and side-band state during bring-up and maintenance.

Questions about this item
Should I choose the MCIO 38P AIC or the U.3 cable end for my server backplane?
The kit includes both: a PCIe x4 Gen 5 AIC with MCIO 38P and a 100CM MCIO 38P to U.3 (SFF-8639) cable, so you connect the AIC to the motherboard and the cable to the drive bay.
What does the 32 GT/s figure mean once the adapter is installed in a live system?
It shows the PCIe 5.0 lane rate per differential pair; the on-board ReDriver provides up to 24 dB equalisation at 16 GHz so the 32 GT/s signal stays clean over the 100CM cable.
How does the SFF-TA-1016 MCIO 38P interface limit performance in practice?
The MCIO 38P connector carries four PCIe 5.0 lanes at 32 GT/s each, so the link is capped at x4 bandwidth rather than x8 or x16.
